Samsung Galaxy S6 Edge black screen, blue light flashing - Galaxy S6 Edge Q&A, Help & Troubleshooting

I have experienced the dreaded Samsung screen of death, 6 days ago I received a text and saw the blue flashing notification light but minutes later when i picked up the phone, the screen was black and not responsive. I have tried every hard and soft reset option, from holding power button and volume buttons to holding all 4 buttons at the same time but nothing has worked. Does anyone have any other suggestions before i send it away for repair? Will allowing the battery to die have any effect? The light is still flashing six days later.

Try to enter in recovery mode (Phone must be off, then hold volume up, home and power)
Look for message on the bottom on the screen
Did you see any unnormal message, like "error" or something?
If you can't turn off the phone, then restart him, holding for min. 7 seconds volume down and power. If you see a screen reaction, then quickly hold the "recovery mode" sequence.

Issues with download mode ATT note

Got my AT&T Note yesterday and it is awesome. I am having some issues getting it into Download Mode. After 100's of tries I am still unsuccesfull. With the phone off I hold the power and volume down buttons at the same time after about 3 seconds the screen flashes and shows the robot and a message about pressing volume up or volume down keys. The screen is only displayed for a second or two, if im fast enough to slide my finger from the volume down to the volume up, it will briefly advance to the next screen and sow the robot again with a few lines of text in the upper right corner with the first line in red. This screen may be displayed for a second or a second and a half and thats it.
any help would be appreciated
Get a jig...

[Q] Htc LCD screen not on

Hey,
so i was at the store, and when I reached for my phone to call someone, it only showed a black screen. When I press the power button, it gives that lit up blue screen like its turned on you know( I guess this is accually a black screen, but its like its powering on)?
I have tried pressing the volume down+power buttons but it doesn't respond to that. The charging lights work and i can unlock the screen, access any app, or google now. I here all the sounds, even my ring tone, but the screen stays black.
Any ideas????

[Q] Need help for my SGS3 (latest cyanogenmod on it)

Hello everyone,
I'm a newbie at rooting.
I have used CM for 3 months but for a week it got a little strange.
Scenario 1) When I push the power button to get to lock screen, the soft buttons' light turn on for a moment but no change happens on screen. I push power button again, the same result. No other respone from my mobile. If I push power button for 10 sec to reset, i see a little green or purple light beam from the bottom right. After a while, it disappears. And still no response. I remove the battery as a last resort and put it back, when I push the power button, it's the same. Little colorful light beams...
Scenario 2) A short time ago, while I was playing a game on it, the screen just turned off and I pushed the power button... as you guess, the story goes on the same way.
It's now off, I couldn't get to it in any way.
What can I do to solve and how?
You guess it's urgent.
Sorry for my poor English, thanks in advance.
Can you restart the phone in download mode, or recovery mode?
I just figured out something:
The phone turned on and I disabled developer settings. After this, when the screen is locked and off and I push the power button, I see nothing on the screen (maybe a little purple or green beam at the right bottom) but the soft buttons turn on. I slide right to unlock without seeing anything, I pass the lock screen and it's now open. (when I touch the screen, the soft buttons turn on again and again as it should be) I just scroll the main pages right and left, push the volume or main button, they work. (it beeps when the sound is max) after 30 - 40 seconds... yay! The screen is on! It's totally the same all the time. It needs time to turn on?
Is it a software problem or is my screen about to break down?
Thanks again!!
it's a software problem. You can either factory reset, run the trim command if you're running android 4.3, or change to a different ROM.

Samsung Galaxy TabS SM-T705 after the screen turns off, it runs on by pressing random

It all started 2 days ago, when watching a clash of clans replay the screen turned off for the energy saving thing. I pressed the power button to bring it back, but the screen didn't turn on, i could hear the game sounds, and the touch screen was working, after the replay ended i was able to tab the buildings in my village and hear the sound they make. I pressed some random combination of buttons, i think its power+volume down and the screen turned on. It happened a second time during that day, and i was able to turn the screen on again. But the day after that trick didn't work and the tablet was stuck with a black screen.
I tried a factory reset, but the menu for it wouldn't appear, the odin menu by the other hand worked fine. The recovery menu should appear when with the tablet turned off you press volume up + home + power in that sequence, and releasing the power button at the samsung logo screen. But the menu never appeared, so i navigated it blindly and i think i managed to reset it, at the next accension i was prompted with the personal information field, name, google account, time settings etc..
The phone started again, with all default settings, and all my files where gone (so im assuming the factory reset worked) but when the screen turns off it doesn't come back by pressing the power button, it comes after trying a few combinations (and again i think it is power + volume down and wait a few seconds).
So im worried it was all in vain, also the screen brightness is bugged, and changes the colors, the become reddish with low brightness and some colors disappear.
Edit: After i let the screen turn off for the third time today, it doesn't come back on. So im back at the black screen...

RN5 Black lit screen after update

Hello everybody,
This morning my Redmi Note 5 ask me install an update.
I did as asked.
Since The phone is not booting, no logo, only a back lit black screen.
When I push the power button for several seconds, the screen turns off then the backlight turns on and that'all.
I try to boot in recovery mode with "Volume Up" and Power Button, but I get the same behavior.
Does anyone have an idea what to do?
Thanks and best regards
I have the same problem, no signs of life. None of the button combinations work. Phone seems to be dead. I flash in EDL mode but can't power on phone
